To all whom t may concern.' l

Be it known that'l, Louis Guieu-ini), a citizen of the Republic ofl France, residing at l Avenue Peterliof, Paris, France, have invented certain new and vuseful Improve-A ments in the Distribution Mechanismof Inn termal-Combustion Motors, of which the' fol lowing is a. specification.

My invention has for its object improvementsiii so called valveless internal combustion motors and is applicable to the type puppet valves. Inthe known distributing mechanisms of this type, the sleeve vis usually subjected to non-*symmetrical forces due to the non-symmetricalarrangement of the the sleeve,`With the result that jamming`v occurs which consumes a portion of the power and produces an oval wear of the parts.

'Moreover the shocks and' abnormal frictional strains between the piston and the .sleeve and other inembers,'cause after a certain lapse of;time, an excessive amount of play which `ves rise to noiseiii working. Further, in a certain number of m01 torshaving a cylindrical reciprocating' sleeve the latter is'exposed to the. pressure of the gas over its entire lower edge. i\c

, .cordin'g to my invention, the sleeve is hung freely on diametrically opposite ends of an oscillating traine wherein the sleeve is able by the action of its own'weight to keep its vertical position at all times, andthe mecha-y nism for actuating the sleeve engages the frame at two opposite ends ofa diameter at right angles'to the diameter of free suspension'. Moreover, the sleeve-thus freely suspended, executes lits ,reciprocating 'move-- ments in a cylindrical chamber which 1s.

closed, i. c., isolated lfrom the' combustion of the motor, so that the gases can only act through thedistributing parts upon the sleeve.

A practical embodimentv fmy invention isvillustrated by way 'of example in the ac-' companying drawings.

, Figure 1 is a diagrammatic elevation of thegeneral arrangement of an internal coinbustion motor lltted with the improved' dis` tributing mechanism. Figs, 2 and 3 are two longitudinal sections taken at richt-angles to each other, respectively along the suspension axis of the-sleeve, vand along the'axis to Whose ends the rocking beam, 1n -the form Specification of Letters Patent.

A head.

modification of the suspensionof the annular sleeve, Fig. is a similar view as Fig. 6 showing a slight modification.

In these several 'gures a. is the motor cyl iiider in which works a piston l). e i c is the end of the combustion chamber formed in the usual maner on a. removable al is the cylindrical distributing sleeve Acapable of' reciprocating. y A

o designates one or more apertuils though which the oil for lubricating the sleeve can flow. and return into the lower framing.' I

" According-to my invention, the kSleeve dA is freely suspended so as to be capable of oscillating, for instance, by' means of two pins or truiiiiionsld in suitable bearings e" provided on an oscillating frame ey By means of thisf'i'ame, thesleeve is connected to theactuatinf.,r mechanism f-g which is attached to the said framein an axis m-a1 (Fig. l) that is at right angles to the pivotal or suspensory axis., d al. As will be readily perccived,'this -manner of suspension. permits. reciprocating the Asleeve without exerting any oblique strain -upon the body of the sleeve, as, the forceA for reciprocating vthe sleeve is always exerted upon the trunnioiis (lL-0l in the vertical axial Aplane common to the cylinder and the sleeve, while'th'e latter, dile to tsbeing freely suspended` will automatically 'center itselfin all positions.' Moreover, also accordiiig to my invention, the sleeve d is guided in a cylindrical chamber le, formed an extension of the wall of the cylinder al between the outer wall of the he'adc and This .chamber h. completely isolates the r`sleeve Yfrom the combustion chamber ofthe ``cylin`de r. 'As a' result of this construction the gases can aetupon' the sleeve d onlyr inside'the distribution parts (Fig. .1). vFurther, the inconsiderable strains to which *the sleeve isfstill subjected, may be balanced in the usual way by providingan -opening of suflicient area inthe removablev head c.

wheels i] and r'having for instance equal diameters while thecwhecl p has a diameter twice that of the wheel q.

The isolated chamber h in which the '15 sleeve d works, may be surrounded in the `usual way by tlie center circulation system common to both the cylinder a and the rej The free susj'vensicm of the trunnions d',

d', instead of being effected by arigid frame,

may be effected by a jointed frame constituted, for instance, .as 'shown in the diagrammatic Fig. (3,V by two parallel rocking beams e having conjugated movemens.- For this Errpfse the ends of the rocking beam may pivoted to the forks of two eccentric thereto, thereby actuatin l connecting rods f, g.
